Linux will seem to be everywhere in 2019

IDG 2019 just might be the Year of Linux — the year in which Linux is fully recognized as the powerhouse it has become. With Linux playing key roles in the Internet of Things (IoT), cloud technology, supercomputing and artificial intelligence (AI), and with a plethora of conferences and new releases on the horizon, Linux is poised to have a very exciting 2019. Let’s examine some of what we can expect to see.To read this article in full, please click here

What to expect of Linux in 2019

2019 just might be the Year of Linux — the year in which Linux is fully recognized as the powerhouse it has become. With Linux playing key roles in the Internet of Things (IoT), cloud technology, supercomputing and artificial intelligence (AI), and with a plethora of conferences and new releases on the horizon, Linux is poised to have a very exciting 2019. Let’s examine some of what we can expect to see.Linux behind the scenes The fact is that most people today are using Linux without ever knowing it — whether on their phones, online when using Google, Facebook, Twitter, GPS devices, and maybe even in their cars, or when using cloud storage for personal or business use. While the presence of Linux on all of these systems may go largely unnoticed by consumers, the role that Linux plays in this market is a sign of how critical it has become.To read this article in full, please click here

Using the Internet of Sound to transfer IoT data via speakers

Some kinds of data should be encoded onto an inaudible, near-ultrasound layer placed on top of normal, audible sounds — a process that could rapidly scale Internet of Things (IoT) adoption, says startup Trillbit.The company says that by doing that kind of overlay, any microphone and speaker is turned into a data-transfer device that then could be used for payments transfers, user authentication, and smart city applications such as digital locks.“There is no common universal protocol to connect Internet of Things,” Trillbit explains on its website. “Speakers [and microphones], which are already in place, and all around us” could perform connections.To read this article in full, please click here

Supercharging my CLI

I spent a lot of time in the terminal. I can’t really explain why; for many things it just feels faster and more comfortable to do them via the command line interface (CLI) instead of via a graphical point-and-click interface. (I’m not totally against GUIs, for some tasks they’re far easier.) As a result, when I find tools that make my CLI experience faster/easier/more powerful, that’s a big boon. Over the last few months, I’ve added some tools to my Fedora laptop that have really added some power and flexibility to my CLI environment. In this post, I want to share some details on these tools and how I’m using them.

The tools I’ve adopted and that I’ll discuss in this post are:

  • powerline-go for an informative CLI prompt
  • rg for faster content searches
  • fd for faster filename searches
  • fzf for fuzzy command history access and faster directory navigation

Let’s take a closer look at each of these.

A More Informative Shell Prompt

There’s been quite a few articles written about powerline, a Python-based utility that provides a much more informative shell prompt. Instead of going down the traditional powerline route, I found powerline-go—a small, statically linked Continue reading

Interview: Active-Active Data Centers with VXLAN and EVPN

Christoph Jaggi asked me a few questions about using VXLAN with EVPN to build data center fabrics and data center interconnects (including active/active data centers). The German version was published on Inside-IT, here’s the English version.

He started with an obvious one:

What is an active-active data center and why would I want to use an active-active data center?

Numerous organizations have multiple data centers for load sharing or disaster recovery purposes. They could use one of their data centers and have the other(s) as warm or cold standby (active/backup setup) or use all data centers at the same time (active/active).
